Atheist being Arrogant

Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not willing? Then he is malevolent. Is he both able and willing? Then whence cometh evil? Is he neither able nor willing? Then why call him God?

-          Epicurus

Why are atheists so arrogant? Atheists are people just like you, some good and some bad. And if you frequent Internet sites frequently, odds are you'll run into more than your share of jerks of all stripes, atheists included.

But what generally motivates this question is when people run into a "strong atheist" who makes the positive assertion that "there is no God". This comes across as an unwarranted and unprecedented assault on the listener and all people who believe in anything spiritual or theological. I suspect it's this feeling of being assaulted that's behind the reflexive charge of arrogance more than anything.

Professor “Richard Dawkins” is best-known as a vociferous critic of religion and a champion for the cause of science. So much so that he is often attacked for being dogmatic himself, in believing only his own preferred worldview should triumph. Some thought his latest book; The Magic of Reality - aimed at children, and explaining the scientific truth behind primitive mythologies - had gone beyond the pale in preaching literalism as the 'one true way'.

He says, that every people can or may experience some kind of trance, according to the right chemical stimulant, it may vary from religious upbringing like for instance the “Virgin Mary” for Catholics and so on. So he decided to take a hallucinogenic drug and try it for himself, as people in the ancient time uses psychoactive plants for shamanistic purposes, maybe “Richard Dawkins” wants a firsthand experience in what may lay in the so called spirit world when you take a drug like this.(http://dailygrail.com/Shamanism/2012/8/Richard-Dawkins-Would-Trip-LSD)

So He took “Graham Hancock” suggestion that he may try the (DMT-containing) shamanic brew from the Amazon, ayahuasca. As “Graham Hancock” quoted "have you ever seriously engaged such techniques to have first-hand experience of what they're talking about, and perhaps even to challenge your own concept of what is real?" and “Dawkins” answered "I would be very curious, I must say, to take, perhaps not that drug, but something like LSD or mescaline," he responded. "I would be prepared to do that under proper medical supervision, if I were absolutely convinced that it would do me no lasting harm. And I would actually like to do it."  In the above statement as said “Dawkins“is somehow curious about the experiment but just like other skeptics, he wants to prove that sometimes what we can see is not all about religion and hallucinating “Gods” nor “angels” but he wants to prove the wonders that the brain can do when used by a right chemical stimulant, that can trigger this functions.
